Hi all,

This is all still very preliminary and could all still go up in flames (it has
only seen hackbench so far). This is mostly the same code I posted yesterday,
but hopefully in a more readable form.

This fixes the SIS_PROP as per the outline here:

  https://lkml.kernel.org/r/20180425153600.GA4043@hirez.programming.kicks-ass.net

and Rohit's suggestion of folding the iteration loops.

For testing I would suggest to ignore the last 3 patches, those are purely
cleanups once the first lot is found to actually work as advertised.
